The mixer shall also be equipped with one unbalanced stereo output and two balanced mono outputs. Yes, unbalanced 1/4" outputs as my power amp accepts 1/4" unbalanced inputs (Fryette 2502). The iO2 EXPRESS sends and receives two audio channels on a single USB cable for simple, universal interface. For the purposes of this discussion, we will deal with line level signals. Remember that 1/4" TS connectors connect to -10 dBV line level equipment, whereas 1/4" TRS connectors expect a +4 dBu line level (for explanation, see the section below on balanced vs. Inputs are balanced XLRs and outputs are stereo RCA connectors. We designed the LGB-1 and LGB-4 to solve an increasingly frustrating problem - how to get the same output level from multiple devices, especially when some devices have inherently low outputs (such as portable audio players and computer sound cards). The aux/phono inputs on the Monitor Station are multipurpose. If you have hum problems, then buy a cheapie passive DI box and use a short XRL patch cable from the output of your preamp to the OUTPUT of the DI, and take your unbalanced line from the INPUT of the DI. And the best part is that you don’t need to shell out your one month salary to buy those super-duper unbalanced audiophile quality cables anymore. 5 dB) THD: < 0. The FP-PA20 features a balanced line level input that may be connected unbalanced. 48V Phantom power switch. output and knocks it down to a balanced mic level which you can then connect to a mic preamp, while also separating the source and destination. The Radial J-Iso™ and Pro-Iso™ are stereo line isolators designed to convert a professional +4dB line level balanced signal to an unbalanced -10dB consumer level device. Even if perfectly matched resistors are assumed, the CMRR of this stage is not infinite; with a TL072 it is about -90 dB, degrading from 100 Hz upwards, due to the limited open- loop gain of the opamp. The Sonic Imagery Labs, Model 898A is a high performance professional grade tool used to convert unbalanced -10 dBV consumer line level audio signals to balanced +4 dBu professional levels - and vice versa. One wire carries the signal and is referred to as the hot line. Frequency response, balanced line output, undithered sine wave at 0 dBFS, Speaker level at 0 dB (same with Speaker level set to -20 and -40 dB). To take the signal of an instrument to mic level an active or passive DI Box can be used. Connect these to external active monitor speak-ers, a PA or recording console or analog DAT recorder inputs. A2517 • Unbalanced Stereo Line Isolation Transformer RCA-RCA. Pre boost amplifier to overdrive the stages following while also engaging a pad on the final output. Trimmer adjusts output level for various input voltage/power levels. I recently ordered a dbx 223s 2-way stereo active crossover which is still on backorder. The TX‑LC2 is the ideal choice in installations requiring the active, isolated mixing of two unbalanced line‑level audio sources to feed a balanced (or unbalanced) audio line. Also, measure the current in each supply phase because the current unbalance is often about 6 to 10 times greater than the voltage unbalance. It is the only product available on the market that provides 8 channels in each direction, simultaneously. If an instrument input is plugged into 3 (or 4), disconnect it.
